Double-Acting and Single-Acting Baking Powder

Double-Acting and Single-Acting Baking Powder If youre like me, youre lucky to pay attention to a recipe enough to notice whether youre supposed to be using baking powder or baking soda. Both ingredients cause baked goods to rise, but they are not interchangeable. Also, there is more than one type of baking powder. You can find single-acting baking powder and double-acting baking powder. You may be wondering how they are different or whether you should use half as much double-acting baking powder as single-acting baking powder. What's the Difference? You use the exactly same amount of double-acting baking powder as you would single-acting baking powder. The difference between the two types of powder is their chemical composition and whether they produce the carbon dioxide gas bubbles that make your baked goods rise when the ingredients are mixed or when the product is heated in the oven. Both types of baking powder produce the same amount of gas, so they are equally effective as leavening agents. Single-acting baking powder reacts with a water-based ingredient to form bubbles as soon as the ingredients are mixed. If you wait too long to bake your food or mix it too long these bubbles will escape and your food will fall flat.Double-acting baking powder produces some bubbles when the ingredients are mixed, but most of the rising occurs once heat is applied. This product is more reliable for home baking because it is harder to overbeat the ingredients and the recipe is less susceptible to failure if you forgot to preheat your oven. Because it is practically failsafe, this is the type of baking powder most often found in stores. Youll encounter single-acting baking powder in commercial applications, plus this is the type of powder you would make if you prepare baking powder yourself.
